21. In electrodynamics , minimal coupling is adequate to account for all electromagnetic interactions. 22. It gets into quantum electrodynamics I'm afraid. 23. Gerhard Rempe is considered a pioneer of the field of cavity quantum electrodynamics . 24. In classical electrodynamics , electric fields are described as electric potential and electric current. 25. In classical electrodynamics , the energy of a charge moving in an applied potential is 26. One is quantum electrodynamics , and the other is the turbulent motion of fluids. 27. More pedestrian approaches include expected behavior in electrodynamics . 28. This comes from the formula for the propagation of a photon in quantum electrodynamics . 29. He published works on philosophy, theology, art theory, mathematics and electrodynamics . 30. Quantum electrodynamics has served as the model and template for subsequent quantum field theories.
